CORN-PLANTER CHECK LENE ANCHOR.

SPECIFICATION forming part of Letters Patent No. 314,432, dated March 24, 1885.

Application filed October 11, 1884. (N0 model.)

T 0 all whom it may concern:

Be it known thatwe, J AMEsWrLsoN CLARK and NORMAN A. PALMER, citizens of the United States, residing at Pataskala, in the county of Licking and State of Ohio, have invented new and useful Improvements in Corn- Planter Oheck-LineAnchors, of which the following is a specification.

Our invention relates to check-row cornplanters, and particularly to the devices, called anchors, for holding the line in position across the field above the ground, and for laying over the line wire or cord by alateral shift or adjustment of said anchor, to obtain a uniform alignment of the rows as the planter crosses the field and returns in a double traverse thereof.

The use of laterally-shifting anchors for check-row lines in corn-planting being well understood, it is deemed only necessary to de scribe the anchor device as improved by us.

Referring to the accompanying drawing, there will be seen one of our improved anchors and a-portion of the check-row line a, connected to the free end of an arm, Z), the other end of which arm is pivoted to the anchor proper, which consists of a stake, a, driven into the ground at the edge of the fieldto be planted.

Unlike the check-row-line anchors which have hitherto been devised, in our improve ment the ground-stake forms a post firmly set in the ground and rising vertically some distance above it, has a staycord, d, connecting its upper end with the arm b of the check-row line, so as to support said arm in an inclined position at the proper height for the line, and allow the arm to be shifted laterally to transfer the line over the middle of This arm is about four feet long, and its flexible stay connection forms the stop to limit the extent of its transferringthrow. For this purpose the arm is pivoted to the side of the stake, so that the planter traversing the line will effect the lateral shifting at the proper time by throwing the arm over from one side of the stake to the other, the arm crossing the top of the stake, so as to carry the check row line and the staycord free of the top of the stake-post. For this purpose the arm is pivoted to the stake, so that its free end will extend some distance above the top of the latter.

It will be understood that the check-row line is under tension sufficient to keep it taut between its two anchor-suspending arms, and to maintain such tension each anchor-arm is provided with a guy or ground stay, 6, securely retained in proper position in the ground by a pin, j, which should be in alignment with the check-row line, so as to brace and support the laterally shifting arms, not only against the tension of the line, but against the strain caused in shifting its position over the top of the stake-post.

In check-row planting, with automaticallyshifting anchors for the check-row line, the arms of said line have been supported by rigid struts resting upon the ground, so as to maintain the line about as highas the planter,the line-arms being pivoted to the groundstakes and supported against the tension of the line by guys or ground stays; but our improved anchor is distinguished in the provision of a flexible stay connecting the linearm with the stake post or anchor-pin at a point some distance above the pivot-connection of said line-arm, whereby the anchorpin is utilized as the means of connecting it with the line-arm by a flexible stopstay having a length equal to half the throw of the lineconnecting arm.

We claim- 1. In an anchor for check-row lines of corn planters, the line-connecting arm pivoted to the stake -post, and connected to it above said pivot by a stay-cord extending from the top of the anchor-post to the free end of the line-arm, whereby to limit the shifting-throw of the latter, substantially as herein set forth.

2. In an anchor for check row lines, the combination of the anchor-post, the line-arm and its guy, with a flexible stay connecting said arm with said anchor-post in a manner to limit the shifting throw of the line-arm, substantially as described.

3. The combination, with the anchorpost, our hands in the presence of two subscribing of theiine arm pivoted to the side thereof, Witnesses. and connected therewith by a flexible stay, so JAMES XVILSON CLARK. as to shift the latter and the line over the top I NORMAN A. PALMER. 5 of said anchor-post, substantially as herein set Witnesses: forth. SAMUEL L. HAGY,

In testimony whereof we have hereunto set NATHAN J. KINNEY.
